Certain Proteins of the Complex Motor That Drives Bacterial Flagella

question 11

Multiple Choice

• C) the motors of bacterial flagella were originally synthesized abiotically.
• D) natural selection can produce new structures by coupling together parts of other structures.
• E) bacteria that possess flagella must have lost the ability to pump certain chemicals across their plasma membranes.
